Abstract

PURPOSE:To enhance the constant-voltage charging characteristics after allowing the captioned battery to stand for a long period of time, by holding a large quantity of electrolytic solution on the surface of an electrode plate neighboring the separator and enhancing the electrification property in case of storage of the captioned battery. CONSTITUTION:A separator 14 and a sheet 15 made of carbon black, graphite or the like having conductive liquid-holding power are sandwiched between a positive plate 11 and a negative plate 12, and 10cc of sulfuric acid-electrolytic solution of specific gravity 1.3 is poured thereinto, and thereafter a resin body 1 and a jar lid 2 are closed and sealed hermetically, then this sealed body is subjected to a formation-charging treatment. By doing this, adhesive property of a collector to an active material is extremely good. After the discharge is finished, the electrolytic solution is held in the sheet 15 part having a conductive liquid-holding power, and this sheet 15 part is effective for suppressing the liquid distribution in an active material layer, so that a stable treatment can be maintained. Consequently, the constant-voltage charging characteristics after allowing said battery to stand for a long period of time can be enhanced.

関丈る。[Detailed Description of the Invention] (a) Field of Industrial Application The invention relates to a lead-acid battery, particularly a so-called retainer set lead-acid battery in which the amount of electrolyte is limited so that there is no free electrolyte. By retaining a large amount of electrolyte on the surfaces of the positive and negative electrode plates adjacent to the separator when the storage battery is left unattended, the formation of PbSO4 in the active material layer adjacent to the current collector is suppressed and the conductivity of the battery is improved. Responsible for things that aim to improve performance.

った。However, if a lead-acid battery is left open for a long period of time with both electrodes open, a chemical reaction will proceed inside the battery case, and the separator will absorb and retain the electrolyte impregnated in the positive and negative electrode plates. The surface of at least one of the positive and negative electrode plates in the tank becomes dry, and when the lead-acid battery is used next time, electrons cannot move smoothly between the i'tTh electrode plate and the negative electrode plate, resulting in reduced conductivity. There was a drawback.

In terms of electrochemical capacity, the amount of sulfuric acid is made smaller than the amount of active material forming the electrode plate. On the other hand, the case of a sealed lead-acid battery is made of synthetic resin in consideration of electrolyte resistance, that is, sulfuric acid resistance. Generally, ABS resin (the acrylic component in the composition has water vapor permeability), AS resin, etc. are commonly used.

鉛蓄電池に比へて短かくなるという欠点を有する。However, this type of synthetic resin is permeable to water and vapor, and when a lead-acid battery is stored for a long period of time, it passes through the wall of the battery case and releases the moisture inside the battery as water vapor. A phenomenon occurs in which the electrolyte concentration increases. This phenomenon is more severe in batteries that have a larger surface area per capacity, or in batteries that cannot be made thicker due to the /J% type, and especially in small and thin batteries, the battery life is shortened due to concentration of the electrolyte. They have the disadvantage of being shorter than lead-acid batteries.

There were also drawbacks.

As is clear from the figure, the discharge efficiency of the conventional battery (B) becomes almost zero after 8 months, whereas the battery of the present invention (A) maintains the discharge efficiency at the time of the start of use.

圧充電特性を極度に悪化きせていた。As described in 1-1 below, in the battery produced by the method of the present invention, the active material layer is placed on the current collector in a wet state, and in order to dry it,
The adhesion between the current collector and the active material layer is extremely good.
In order to carry out chemical charging in the still state, the current flowing through the oxidation ensures strong integration, and uniform adhesion is achieved over the entire surface of the current collector and active material layer. In addition, in conventional batteries, when left in a discharged state for a long period of time, sulfate ions (SO4'-) in the electrolyte that remain as a result of changes over time during storage can cause problems at the interface between the current collector and the active material layer, that is, the adhesion. Creep of the electrolytic solution occurred in the slow portion, producing PbSO4, and by leaving the battery for a long period of time, the inactivation of PbSO4 progressed, and the constant voltage charging characteristics were extremely deteriorated.

Because it has the effect of suppressing the distribution of the electrolyte, especially in the active material layer that is in close contact with the current collector, P due to electrolyte creep during storage is
bSO4 generation does not occur at the interface between the current collector and the active material layer,
A stable state can be maintained. As a result, the charging characteristics after being left for a long period of time are also very good and stable.
